National Car Rental Coupons & Promo Codes in November 2026

There's a military discount, but no senior one. National Car gives lower leisure rates to active-duty military, veterans, retirees, and federal employees, though it doesn't offer an AARP or age-based rate, so there's nothing for being 50 or older. If you're shopping as a senior, you're better off comparing their regular price against what other brands charge or relying on their weekly rental deals.

To get the military rate, add the government/military leisure account number to your reservation before you check availability, and it comes off automatically. Based on our checks, they never publish the exact discount since it changes by status and location. So the real way to know what you'll pay is to punch in the number and look at your total.

If you're renting on official orders instead of for personal travel, mention that when you book, since it's usually handled as a separate and often bigger discount.

Yes, and since it's free, there's really no reason not to join. The biggest draw is the Emerald Aisle. You book a midsize, then take any midsize-or-larger car on the aisle for that same midsize price, so you're basically getting a free upgrade every time. You also pick up one credit per rental and a free day for every seven, and since those credits never expire, even the occasional trip keeps nudging you closer to a free rental.

It's most rewarding for anyone who rents more than once a year. One trip a year won't stack up much, but that free upgrade can more than justify joining on your very first rental. Rent often, and the higher tiers, like Executive, help even more, dropping the free-day mark to six credits and adding guaranteed upgrades.
